TYPE-BAR HANGER.

SPECIFICATION forming part of Letters Patent No. 448,690, dated March24, 1891.

Application filed April 25, 1890. Serial No. 349,454. (No model.)

T0 62% whom it may concern:

Be it known that I, GEORGE F. STILLMAN, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Type-Bar Hangers, of which the following, taken inconnection with'the accompanying drawings, is a full, clear, and exactdescription.

My invention relates to type-writing machines, and espeoiallyto themountings of the type-bars upon the type-bar ring in that class commonlyknown as center-strike lever-ma chines. My object is to improve themounting and lncrease the length of the shaft carrying the type-barswithout increasing that of the bars themselves, thereby reducing thesize of the ring and increasing the number of bars with out increasingtheir length, and affording means for a more perfect adjustment andalignment by mounting the bars in banks of two or more, each upon aseparate rock-shaft, mounted in diverging linein bearings adjustablevertically to vary any shaft more or less to or from a horizontal and toadjust the tension upon the bearings.

My invention consists in the several novel features of construction andoperation hereinafter described, and which are specifically set forth inthe claims hereunto annexed.

It is constructed as follows, reference being had to the accompanyingdrawings,in which- Figure 1 is a top plan view of a portion of thetype-bar ring upon which three of my hangers are mounted. Fig. 2 is anenlarged front elevation of a hanger and a vertical bank of threeshafts, each carrying a typebar. Fig. 3 is a side elevation of the same.Fig. 4: is a side elevation of a gang of two hangers arranged. in ahorizontal plane, showing the connecting-rods in dotted lines. Fig. 5 isa View of the front type-bar of this horizontal bank. .Fi 6 is a view ofthe rear typebar, showing it bent or cut away, so as to permit itstype-arm to strike the platen. Fig. 7 is a rear elevation of al'ltllgQD-flflllltl, showing the screws holding theparts togetherinclined. Fig.8 is atop view of thehanger shown in Fig. 4. with thetype-bars removed. Fig. 9 is a top view of the form of hanger shown inFig. 3

' with the type-bars removed.

A is the typebar ring or portion of the top plate of the machine, andupon its upper face I mount the hanger or hanger frame B. This hangerconsists of two angular sections 1 l and 2 2, of light construction, andeach is provided in its front end with slotways 8, creating points 4.The rock-shafts 5 are journaled in these points, so that each pair ofpoints is an independenthanger and supports an independent type-bar. Atype-bar 6 is connected or secured to each shaft, and each shaft isprovided with a rearward crank-arm 7, to which a connecting-rod isattach ed in the ordinary way, or the type-bar may have arearwardly-projecting ear to which a connectingrod is attached. When thetype-bars are mounted in a bank or gang of three, these shafts aremounted so as to bring the center one horizontal and the upper and lowerones on lines diverging therefrom and from each other, and when in abank of two then bot-h diverge from each other. The effect of suchdiverging is to cause the type-arms to more readily clear each otherwhen in operation.

In Fig. 2 it will be seen that the slotways 3 upon the left of thehanger are narrower than the slotways upon the right of the hanger. Thiscauses the upper and lower rocleshafts 'to diverge from each other fromthe left, and

thus it will be seen that when the type-bar of the upper shaftis forcedupward in the operation of the machine it will strike the platen at apoint a little to the left of the position whichit occupies when atrest, and when the type-bar 6 on the lower shaft is operated it willstrike the platen at a position a little to the right of the positionwhich it occupies when at rest. The middle rock-shaft is hung in thehanger level orat right angles to the perpendicular sides of the hanger,and it will thus be seen that the diverging of the upper and lowerrock-shafts can be so adjusted that the type will strike the commoncenter. It will be observed that either of the points 4 can be forciblybent up or down or twisted to change the levels of divergence of eitherend of the rock-shaft, effecting a very full, accurate, and secureadjustment of the rockshafts.

hen I desire to mount the type-bars in a horizontal plane, I constructthe hanger narrower than when I desire to mount them in a vertical bank,omitting the slotways, as shown in Figs. -.t and S. The forward type-baris constructed substantially like the type-bar used in the verticalbanks; but the rear bar is bent or cut away to pass below the forwardrock-shaft, so as to permit of the type-arm striking the platen. (Theform of this typebar is shown in Fig. (5.) The sections of the hangerare so arranged that the base of one lies upon the base of the other, asshown in Fig. 7, and are secured together and to the ring by screws 9,which are inclined so that when they are forced home the sections aredrawn together horizontally and serve to produce a tension to keep themtogether and hold it more securely.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. A type-bar hanger consisting of two sections, each composed of a baseand an upturned side, the base of one lying upon the base of the other,the sides standing vertical and substantially parallel, and means for socuring the bases together adjustably.

L. A type-bar hanger consistingof two parts, each having a base andupturned side radially slotted, and means for securing them together andto the type-bar ring, as set forth.

3. The combination of. a type-bar hanger consisting of two sections,each having a base and upturned side, diverging rock -shafts mountedtherein, and means for securing the sections of the hanger together andto the type-bar ring, as set forth.

t. The combination of a type-bar hanger consisting of two sections, eachhaving a base and upturned side radially slotted to form adjustablepoints, diverging rock-shafts in0unt ed in the adj ustablo pointscreated by the slotway in said sides, and means for securing thesections together and to the type-bar ring, as set forth.

5. A type-bar ring, a hanger consisting of two sections, each havingabase and upturned side, adjustable bearings in the sides of thehanger-sectioils, means for securing them together and to the type-barring, multiple rockshafts mounted in said adjustable bearings, andtype-bars secured to the rock-shafts, in combination, as set forth.

In witness whereof I have hereunto set my hand this 18th day of October,1889.
